A linear guide apparatus includes a guide rail 4 and a slider 10. At least one of grooves provided on the guide rail 4 and the slider 10 is a groove having a V-like cross sectional shape formed by a combination of two curved surfaces having a circular arc cross sectional shape. One of the two curved surfaces is in contact with balls 7 when the apparatus is in use, and the other curved surface is not in contact with the balls 7 when the apparatus is in use. The depth from an end of one curved surface with respect to the circumferential direction to the bottom of the groove is larger than the depth from an end of the other curved surface with respect to the circumferential direction to the bottom of the groove. |
